Marlin (POND) is an open protocol that provides high-performance programmable network infrastructure for DeFi and Web 3.0. Co-founded by former Microsoft, Samsung, Cisco engineers and researchers from MIT and the Ethereum Foundation, Marlin is an open protocol that provides a high-performance programmable network infrastructure for Web 3.0. It enables faster transfer of blocks, transactions and data between miners, full nodes and layer 0 users, making the dApp experience smoother and more convenient. The core of the Marlin protocol is a network of relay nodes that communicate using specialized path conditioning, dynamic flow control, and multi-path routing techniques to achieve superior performance on weakly connected networks. Being platform-agnostic, its plug-and-play network modules are interoperable with a wide range of consensus algorithms. Marlin's mission is to provide Web 2-like performance in Web 3 without sacrificing the core principles of decentralization and security.
